DRIVING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 667,848, dated February 12, 1901.

Application filed July 3, 1900. Serial No. 22,417. (No modehl To all whom it may concern:

Be it known that I, HENRY W. MORGAN, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Driving Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention has for its object to provide improved driving or friction mechanism particularly adapted for operating the devices for raising and lowering the table or work-support of box-nailing machi nessuch, for instance, as shown in my Patent No. 587,321, granted August 3, 1897; and it consists in certain improvements and combination of parts, whereby the construction of the device as a whole is simplified and the operator is enabled to operate the driving devices, and thereby cause the raising and lowering of the table expeditiously and with the exercise of very slight force, all as will be hereinafter described, and the novel features pointed out in the claims at the end of the specification.

In the accompanying drawings, Figure 1 is a side elevation of a portion of a nailing-machine such as shown in my before-mentioned patent with my present invention applied thereto; Fig. 2, an enlarged View of the driving mechanism; Fig. 3, a sectional view on the line 5000 of Fig. 2; Fig. 4, a sectional view on the line y y of Fig. 3 and looking to the right; Fig. 5, a reduced sectional view on the line 2 a of Fig. 3 looking to the left; Fig. 6, a sectional view of a chain-tightener.

Similar reference-numerals in the several figures indicate similar parts.

The nailing-machine to which the invention is shown applied is substantially the same as that in my former patent, 1 indicating the main frame, provided with the vertically-movable table or work-support 2, operating on suitable guides and having at its lower end a projection or nut 3, through which passes a vertical screw 4, stepped at the lower end in the main frame and provided near its upper end with a worm-wheel operated by a worm on the shaft 5, mounted on suitable hearings in the main frame. The shaft 5 is also provided witha sprocket-wheel 6, around which extends a chain or other suitable power-transmitting device 7, extending also around a sprocketwheel 8, loose on the stud or pin 9, secured by a bolt 10 in a bracket or frame 11. This frame 11 is bolted or otherwise preferably removably secured to the foot 12 of the main frame of the machine in its present embodiment and could be made as a separate article and applied to any other machine in relation to a suitable operating part or pulley.

13 indicates a driving-shaft, in the present embodiment of the invention being the constantly-rotating driving-shaft of the nailingmachine; but as far as my present invention is concerned it may be of any suitable description and driven in any suitable manner. At the end of the shaft 13 is a pulley l4, having an overhanging rim, as shown, extending toward and over the stud or pin 9, which latter is arranged eccentrically of the pulley center, the inner surface of this rim being smooth and adapted to cooperate with friction-driven rollers 15 and 16.

17 indicates a rocking or oscillatory frame or casting pivoted upon the stud 9, provided on its upper side with a handle and extension 18 for tilting or turning it on the said shaft, said handle being provided with the springoperated locking-bolt 19, adapted to cooperate with the notch 20, formed in the upper segmental portion of an extension of the bracket or support 11. Mounted in suitable bearings in the sides of the frame 17 are the journals or stationary arbors 21, upon which are located the friction-rollers 15 and 16, said rollers being provided with gears 22 and 23, respectively, formed upon or secured to them. Also journaled upon a shaft or bearing 24, extending between the sides of the frame 17, is a gear 25, meshing with gear 23 and a gear 26, rotating loosely upon the stud 9 and connected to or formed with the sprocket or chain wheel 8, so as to rotate the latter. The rollers 15 and 16 and a portion of the frame 17 are, as stated, located Within the overhanging rim of the pulley l4, and in normal position, with the handle 18 extending vertically, as shown in Figs. 1 and 2, both of the friction-wheels 15 and 16 are out of contact with the rim of the said pulley 14; but-if the operator desires to cause, say, the elevation of the work table or support he operates the bandle 18 to the right in Fig. 2, bringing the'fric-' tion-pulley in to contact with the inner side of the rim of the driving-pulley 14,..w'hich is rotated in the direction indicated by the arrowin Fig. 2. This frictional engagement of the Wheels 14 and 15 will cause the latter to be rotated in the direction indicated by the arrow in-Figs..2.and 5 and through. the gears 22 and 26'will cause the sprocket-wheel 8 to' rotate in the direction indicatedby the (arrow:

in Fig. 4, operating the chain 7 upon the wormshaftin a direction to move the table or Worksupport upward. When'it is desired to operate the table in the opposite direction, the op: erator throws the handle 18 tothe left,.Fig; .2, causing the wheel 16 to engage with the overhangingrim of the driving-pulley 14, from whence motion will be transmitted through the gears 23 and 25 to the gear 26 and the sprocket-wheel connected thereto, so as to move the chain in the opposite direction, as will be understood.

In the reversible driving connection shown the parts are fewand simple, and the friction wheels or pulleys being located'withinthe rim of the driving-wheel are protected and concealed and not liable to injure the operator. The upper surfaces of the gears in-the oscillatory bracket or frame 17 are further covered orprotected by a metal plate .28, secured by boltsor screws or otherwise, as shown particularly in Fig. 5. This form of-reversible driving connection can be applied to other forms 'of machinery or used in other connections, and I do not desire to confine myinvention to its application to nailing-machines or to any particular type, although I-have found in practice that it is well adapted for the purpose described.

' It will of course be understood that the wheel 8 could be used as the driver and the pulley 14 as the driven wheel,if desired,though I prefer to drive in the opposite direction, as

shown.-

The wheel14 might be a merebelt-wheel, if desired, connectedto the machine to be operated or to a prime mover.

, InjFig. 6 I have shown a sectional view of. a belt-tightening device embodying an armor bracket .30, carrying at its outer end aloose tightener wheel or pulley 31 and adjustably secured to a segmental arm 32 onthe main frame, the clamping device'embodying a movable' plate 33, secured by a bolt 34.
